Intensive care unit deals with data that are dynamic in nature like real time measurement of health condition to laboratory test data that are continuously
changes accordingly with time. Artificial intelligence (AI’s) potential ability to perform complex pattern analyses using large volumes of data. Generated
pattern discovers the new symptoms of the disease in the Intensive care units (ICUs), helps the doctors to prescribe the new drug discovery which is
helpful to intelligent use. Currently research work has been focused in the ICU making more efficient clinical workflow by generation of high-risk
patterns from improved high volumes of data. Emerging area of AI in the ICU includes mortality prediction, uses of powerful sensors, new drug
discovery, prediction of length of stay and legal role in uses of drugs for severity of disease. This review focuses latest application of AI drugs and
other relevant issues for the ICU.
The goal of hemodynamic monitoring is to assess the cardiovascular state of the patient, define their reserve and monitor response to treatments and time. Resuscitation efforts are essentially aimed at restoring and sustaining tissue wellness through maintaining an adequate amount of oxygenated blood flow to the metabolically active tissues. We need to monitor pressure, flow and function. To accomplish these goals one must be able to measure arterial pressure and all its components (i.e. waveforms), cardiac output and stroke volume as well as the adequacy of flow. Presently, there are several devices that can estimate the arterial pressure waveform from a finger plethysmographic device. They are very accurate until profound circulatory collapse makes peripheral pulse not representative of central pressures. These devices can also estimate stroke volume by intuiting the arterial pressure waveform in a fashion similar to that performed by the numerous minimally invasive hemodynamic monitoring devices we now have now. These non-invasive devices can quantify functional hemodynamic monitoring dynamic parameters. Also, pulse oximeter pleth density signals vary with pulse volume into the finger or skin and the pleth variability can also be used as a surrogate of pulse pressure variation. Furthermore, bioreactance can measure both cardiac output and intrathoracic fluid content through surface electrodes. Finally, end-tidal CO2 transiently varies with venous return, increasing if blood flow increases. So both eh bioreactance device and end-tidal CO2 can be used to identify cardiac output changes in response to a passive leg raising maneuver. Thus, one can measure arterial pressure waveforms and cardiac output continuously, assess volume responsiveness and monitor therapy. Finally, the dynamic changes in tissue O2 saturation (StO2) measured by near infrared spectroscopy of the thenar eminence during a vascular occlusion test defines peripheral circulatory insufficiency and local blood flow independent of arterial pressure. Furthermore, heart rate variability decreases with increasing cardiovascular stress and can be readily measured in real time from the R-R intervals of the surface ECG signal. Finally, the measure of urine output, skin temperature and sensorium all define effective tissue blood flow as reasonable end-points to resuscitation, if the patient is not overwhelmingly ill. When these measures are coupled to a treatment approach know to improve outcome, there is little reason to believe that such completely non-invasive approaches will be inferior to invasive ones in the management of the critically ill patient.

Telemedicine, the remote delivery of healthcare services using telecommunications technology, has gained significant prominence in recent years, including its application in clinical research. Telemedicine in clinical research refers to the use of virtual visits, remote monitoring, and telecommunication tools to facilitate participant enrollment, data collection, study assessments, and monitoring in research studies. Here are some key aspects and benefits of telemedicine in clinical research:
Participant Recruitment and Access:
Telemedicine enables researchers to expand their participant pool beyond geographical limitations. By leveraging telecommunication tools, researchers can reach individuals who may face challenges with physical access to study sites, such as those living in remote areas or individuals with mobility issues. This broader reach enhances participant recruitment and diversity, contributing to the generalizability and representativeness of research findings.
Remote Study Visits and Data Collection:
Telemedicine allows for remote study visits, eliminating the need for participants to travel to study sites. Through video consultations and remote assessments, researchers can conduct interviews, collect data, perform examinations, and administer questionnaires remotely. This approach reduces participant burden, increases convenience, and enhances compliance by minimizing the time and effort required for in-person visits.
Real-Time Monitoring and Data Capture:
Telemedicine facilitates the collection of real-time data by remotely monitoring participants' health status and adherence to study protocols. Wearable devices, mobile health applications, and sensors can be used to capture vital signs, medication adherence, activity levels, and other relevant data. Researchers can access and analyze this data in real-time, enabling early detection of adverse events, improving safety monitoring, and enhancing the accuracy and completeness of data collection.
Patient Engagement and Retention:
Telemedicine enhances patient engagement by providing more frequent interactions with study staff and personalized support. Regular virtual check-ins, educational sessions, and feedback can strengthen the participant-researcher relationship, leading to increased participant satisfaction and retention. Telemedicine also offers flexibility in scheduling visits, reducing missed appointments, and improving overall study adherence.
Cost and Time Efficiency:
Telemedicine can reduce the overall cost and time associated with conducting clinical research. It eliminates or reduces travel expenses for participants and reduces the need for physical study site infrastructure.
Medical imaging is part of a changing medical environment, a changing
patient environment and consequently a new medical world. In the
recent decennium one of the most important changes in radiology is the
conversion from analogue to digital. In no time medical images have
become interchangeable through the digital highway and could be postprocessed
in a different location. Teleradiology has become a reality
since then. We have seen the maturation of commercial international
teleradiology companies offering a wide portfolio of services. Another
aspect is the availability of image data for all medical specialties beyond
radiology and beyond the regular medical disciplines. An increasing
number of surgical or oncological specialties and even pharmaceutical
companies increasingly use image data to prepare a strategy for
operative procedures, to choose the right therapy, to decide which
prosthesis to the best to use, for follow-up or for post-processing
purposes. They are supported by many new techniques and software.
An increasing number of medical computer applications such as complex
navigation and visualisation tools based upon digital images is already
in clinical use or under development. Another trend is the increasing
interest in E-health and telemedicine in Europe, also among European
policy makers. Now we see mobile health that brings care directly into
the patient environment. The purpose of this presentation is to give a
comprehensive overview of and insight into these new developments and
to create awareness among radiologists of the increasing importance of
integration of medical imaging in a multidisciplinary environment.
Artificial intelligence (AI), machine learning, and data science have started to shape the delivery of health services. We see this in every critical step, from patient scheduling management to physically assisted surgery.
Critical care involves highly complex decision making. It is by nature data-intense. Despite the growth of critical care, however, the basic approach of data collection and management has remained largely unchanged over the past 40 years. Large volumes of data are collected from disparate sources and reviewed usually retrospectively; and even that is difficult.
Understanding the dynamics of critical illness requires precisely time-stamped physiologic data (sampled frequently enough to accurately recreate the detail of physiologic waveforms) integrated with clinical context and processed with a wide array of linear and nonlinear analytical tools.

A study on “impact of artificial intelligence in covid19 diagnosis”Dr. C.V. Suresh Babu
Although the lungs are one of the most vital organs in the body, they are vulnerable to infection and injury. COVID-19 has put the entire world in an unprecedented difficult situation, bringing life to a halt and claiming thousands of lives all across the world. Medical imaging, such as X-rays and computed tomography (CT), is essential in the global fight against COVID-19, and newly emerging artificial intelligence (AI) technologies are boosting the power of imaging tools and assisting medical specialists. AI can improve job efficiency by precisely identifying infections in X-ray and CT images and allowing further measurement. We focus on the integration of AI with X-ray and CT, both of which are routinely used in frontline hospitals, to reflect the most recent progress in medical imaging and radiology combating COVID-19.
Revolutionizing health through technology involves leveraging advanced tools, digital solutions, and data analytics to enhance healthcare delivery and outcomes. Telemedicine offers remote consultations and monitoring, ensuring broader access to healthcare. Wearable devices and health apps enable individuals to track their health parameters in real-time. Artificial intelligence aids in diagnostics, drug discovery, and personalized treatment plans.
The most fundamental expectation from the healthcare sector is that it provides a safe and reliable environment to serve patients. Medical supplies and equipment have also improved with technological advancements, making them easier to use, providing a better experience, and increasing their longevity. With advancement in technology, medical services can also be tracked for efficiency.

i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

27. Opportunities for the Future of Health
(of course in the ICU)
Joint enterprise of patients & health professionals & others
(cross fertilization) using digital technologies: big data,
connectivity and artificial intelligence
New forms of technology: sensors and mobile apps for
continuous monitoring, early interventions and immediate
corrections
New players: Small start ups (drive innovation) & Google
and Apple (services providers) instead of big manufacturers
(marketing and distribution): collaboration versus competition
Finding successful business models: adding services to the
portfolio, system efficiencies and long term value
In the ICU we must go from
Volume to Value !!
